Despite the scandal which exploded to engulf the entire church, he was given an honorary position at the Basilica Santa Maria Maggiore, in Rome.

Every Cardinal has a Rome-diocese church at which he conducts services when that Cardinal is in Rome, or so I understand.

So by barring Law from one of the perks of Law's cardinalate, Francis is rather forcefully inviting Law to disappear. (I don't know whether a pope can dismiss a cardinal. I tend to doubt it, particularly where the cardinal at issue was given that office by a prior pope. Anyone know?)
